IMPROVEMENT IN CARRIAGE-JACKSV.

TO ALL WI-IOM ITM-AY` CONCERN:

Be it known that I, -OLNEY CHURCHILL, of Canton, in the county of Bradford, anu vaste of Pennsylvania, have invented certain new and useful Improvements in Lever-Jacks for Wagons or Carriages; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, meking'part of this specification, and to the letters of reference marked thereon, like letters indicating like psrts'wherever they occur.

To enable'others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists in a novel construction of a lever-jack, for use in connection with wagons or carriages, whereby I am enabled to produce a very cheap, simple, and eiicient article.

Figure lis a vertical section taken on the line :v :c of iig. 2.

FigurcQ, a horizontal section taken on the line z .e of g. 1.

Figures 3 and 4 representa modification of the same.

In constructing my improved device, I take a small wooden' bar, B, and form in its front side, either hy cutting away'a portion, or by fastening narrow strips on the front at each edge, a dat groove, to receive a strap, b, and in the upper end of this bar, Ijournal or mount a pulley, a, which should be equal in width to theA strap,

,ftholower end being secured to Va vsmall block or piece of plank, A:,=to form a Ahase to support the apparatus, and

prevent it from Vsinking into the ground, when supporting the weight of the wagon or other vehicle, as reprcsented in fig.,1. Ithen provide another bar, C, and placing it upright against the front face of' the bar B, enclose it by a metal clasp, c, which is secured rigidly to the bar B, near its upper end, asshown in figs. 1 and 2, the bar C sliding loosely up and down in the clasp c. I provide a strong strap, b, and attach oneend securely to the back side offthe bar C near its lower end, and pass its opposite end up over the pulley a, and down a shortdistance on the rear side of bar B, and attach to its end a ring, o, of proper size to encircle and slipeasily von a lever, L, as represe'nted in iig. 1, this lever being provided wiihone or more notches or projections, to prevent the ring o from slipping when the lever is inclined, as shown 'in iig. 1. Inthe bar B, I bore a series of holes, e, of proper size to permit the end of thelever L to be inserted therein, and hold the same .rigidly in position, when shoved-fairly in, or, if preferred, the front bar C may be made somewhat widerthan the bar B, as represented in fig. 4, which is atop plan view, the clasp e being slightly changed in form, as there represented, to correspond. A seriesof notches may then be cut in the projecting edge of the bar C, and a pawl, mpivoted to the side of bar B, so as Vto engage in the notches, when the bar C is raised, and thus hold it up, as represented in fig. 3, which is a side elevation, representing this modification. .I r c To use my improved jack it is placed in position, and `the upper end of bai` C placed under the axle of the wagon or carriage. The lever L is then slipped into the ring o, and its outer s nd lis raised until its opposite end will enter one ofthe holes e a short distance, when its outer end is depressed, thereby drawing the strap b down over thc pulley a, wh'crchy the har C, with Athe axle resting on it, is elevated, and when the lever is brought to a horizontal position, as indicated hy the red lines in iig. 1, it is shoved entirely into the hole e, which then holds it` securelyrin place. If the pawl n he used, then the shoving of the lever L into the hole for the purpose of locking it in position may bel omitted, if desired. l I

When not in use, the lever L is removed from the ring', and its end inserted in alhole bored in the front part ofthe base, A, as indicated in red in iig. 1, and the bar C being shoved down, the whole is the'nin a compact form, occupying but little space, and can be readily stored nnderthe seat, and carried with thevehicle, for use on the journey, if desired. Being composed of wood, it is unusuallyr light, und hence is more convenient for useor transportation, than the ordinary articles 4of its kind, especially when made of metal.

Having thus described my invention, what I claim, is

A lever-jack, when constructed and operating substantially as shown and described.
